Application filed June 9, 1919. Serial No. 30,769.

llze the turbine or any other power transmltting mechanism.

Other objects and 'advantages of the invention will become apparent during the course ot' the following description.

ln the accompanying drawing forming a part of the application B designates a liquid oxygen tank having a pamage U inthe top thereof whereby the` oxygen gas will esis provided with an outlet cape from the tank B into a gas chamber L which entirely7 surrounds the liquid oxygen tank. From this chamber, the oxygen gas is conveyed by suitable piping H to the lower end of a water tank M, which is supplied with water by the Water reservoir E communicating with the lower end of the tank M by means of a. conduit E. The oxygen gas is inoistened by passing up through the water contained in the tank M and is then directed through an opening F in the nozzle N to combine with liquid fuel entering the combustion chamber A through a' conduit l". It will be noted that the outlet end of the tank `M extends into the opening 1" and nozzle N of the combustion chamber and the opposite end of the tank com municates with thc bott-om of the' fuel tank (l. A by-pass pipe C (he upper end of the water tank M and the upper end of the fuel tank to permit of the entrance of a certain amount of oxygen into the fucl tank to mix with the fuel contained therein. A safety release valve R 'is provided for the combustion chamber to prevent the pressure from rising to a dangerous point and to permit the apparatus to operate under other conditions.

The bottom of the combustion chamber A opening T which communicates with an engine D such as a rotary turbine by a conduit T.

The excommunicates with lcrease the combustible with said Water haust from the turbine passes up throu h an exhaust pipe G which damper Ur whereby the exhaust gas may'be either exhausted to the atmosphere or to a heating chamber K surrounding the gps chamber L. The top of the vheating chamber is provided with a provided with a, closure whereby li uid Oxygen may be entered into the tank From the foregoing, it Will be obvious that the exhaust gases from theengine may be admitted into the heating chamber to heat the liquid oxygen suffioientlyto cause vaporization thereof. It will also be noted that the combustion chamber 1s partially submerged in the Water contained in the Water tank and consequently keeps the combustion chamber A at a comparatively low ltemperature. The combustion chamber is provided With a hand hole covered by a removable nlug V whereby a match may combustion chamber to mixture entering through 'fthe inlet opening F.

As "a gas is created by the oxygen vapor combining with the liquid fuel at the nozzle F,

beingr ignited will burn in combustion chamber As there will be practically amend` less supply of liquid fuel and oxygen vapor,

the flame will continue to burn in the combustion chamber thereby creating a pressure,

therein. The burning gases will expand and pressure Will be exert-eden the rotor of the rotary turbine to cause the same to be set into motion. By the provision of the conduit T all pressure in the combustion chamber is caused to be concentrated upon v.the rotor of the turbine so that movement will be im'- parted to. the latter. ber A will be maintained in as cool a space as possible by the Water surrounding` the same, but when the combustion chamber becomes iiitensely hot, it willv heat the Waterin the jacket M and steam Will be created which will combine with the oxygen vapor and be admitted into the combustion chamber to inqualities of the gas created at the nozzle'F.

What I claim as my invention is l. The combination of a'combustion ehamber, a Water jacket surrounding the same; of an oxygen vapor chamber communicating jacket whereby the vapor is through the Water therein,

caused to travel chamber having a nozzle said combustion be inserted ntdthe ignite the gaseous 9s' j The combustion chain- ,I 10o ion communicating with the upper end of the Water jacket, and means for supplying liquid 'fuel to the nozzle whereby a combustible gas is created in the combustion chamber and which is adapted to he ignited for creating pressure in said combustion chamber, and means for converting` the pressure into mechanical energy.

2. The combination with a combustion chamlier. a water jacket therefor having vcommunication with the combustion chainand means connected to said last the chamber surrounding the liquid oxygen chamber to pro* mote the vaporizaizion of the liquid oxygen.

3. The combination with a combustion chamber; of a liquid oxygen tank. an oxygen vapor chamber surrounding,` said liquid oxygen tank, means for conveying said oxygen vapor to the combustion chamber, an exhausil chamber surrounding the oxygen Vapor chamber, means for combining the oxygen `vapor in the combustion chamber with 'fuel Jfor creating a combustible gas, means 'for converting the pressure created by the burning gases in said combustion chamber into mechanical ci1e1gy,'and an eX- haust pipe communicating' said last named means with the exhaust chamber whereby the vaporization of the. liquid oxygen may he promoted vhen desired.
